The very first release of PlatyPS was back in 2016. Ever since that release, no stable v1.0.0 has been released. But out of the shadows, a new PowerShell module rose: Microsoft.PowerShell.PlatyPS.
This book walks you through Microsoft.PowerShell.PlatyPS, the modern module for writing and maintaining PowerShell help content. It’s based on real-world experience and best practices. The book dives deep into its new structured object model and provides a ton of exercises for you to explore.
